EkoLum case study in Coquimbo, Chile

1. Project for Energy-Efficient Street
Lighting in Coquimbo with
LONWORKS® Network
The LonWorks protocol is used extensively for communication and control of the luminaries via the
existing electrical wiring (PLC), without need for additional cables.
All the luminaires can be remotely controlled by accessing a server controlled by the EkoLUM software
(an exclusive of EkoPLC). This communication is enabled by installing a segment gateway with USB
connectivity into the electrical control panel. The gateway has USB connectivity and comes with a
GPRS modem. With the additional installation of a controller for each luminaire, we obtain in real time
information, monitoring, and control of each luminaire, all without the need to route additional cables.
The solution can automatically identifiy failed
lamps, and enables real-time control to reduce
onsite operations. It can also increase light
quality by using electronic dimmable ballasts that
drive the lamps more efficiently and make them
last longer.
Smart Thinking
The system could use new lower-wattage
streetlights that last longer, offer higher-quality
lighting, and can communicate over a network.
Each Light can includes a smart electronic ballast
that identifies lamp and ballast failures; measures
energy use, running hours, and voltage; and
enables remote command through the power line

2. Add smart streetlights embedded with LonWorks technology
Each luminaire in the street lighting network includes a ballast thatʼs been integrated with one of our
power line smart transceivers. This lets it automatically detect lamp failures, dim the light in 0.5-
percent increments, and report vital statistics such as consumed energy, lamp-burning hours, voltage,
current, and ballast temperature. It also lets each luminaire act as its own energy submeter. Numerous
manufacturers produce luminaires and ballasts based on our technology, and new features are
constantly being added. For example, LED lights can flash in a predetermined sequence to help route
emergency traffic or help emergency response personnel locate an accident scene more quickly.
Ballasts communicate over a cityʼs existing power lines via our power line signaling technology — the
worldʼs most proven and reliable networking solution, with an installed basd of over 32 million units.
This technology, which uses ISO/IEC 14908-1 and -2 standards, is immune to the trucks, hills, trees,
weather, and new construction that can bring a radio-frequency-based system to its knees.

Control your entire network with easy-to-use host software. These Ekolum software solution , offer a
highly visual graphical environment to help city personnel manage WAN communications, track
failures, check system health, automatically install new SmartServers, and collect, organize, and store
data. They also extend to higher-level applications, for use with service databases, billing, notification,
energy management, and other existing systems.
